What you want is something like this:

/ip firewall filter add chain=forward p2p=bit-torrent action=drop

Or, for those of you using WinBox:

  • Navigate to IP > Firewall
  • Click on the big red plus
  • General > Chain: forward
  • General > P2P: all-p2p
  • Action > Action: drop

Credit goes to Atari – without their terribly broken digital download service, I would’ve never been forced to accidentally test this rule. :p

nameserver #.#.#.#
nameserver #.#.#.#

Naturally, replace #.#.#.# with the IP addresses of your nameservers.

/etc/sysconfig/network:

NETWORKING=yes
HOSTNAME=BOX
DOMAIN=DOMAIN.FOO

HOSTNAME is, of course, where you put the hostname of your box. This should not be a FQDN; the domain should end up in the DOMAIN variable.

/etc/sysconfig/network-scripts/ifcfg-eth0:

DEVICE=eth0
BOOTPROTO=static
IPADDR=172.16.42.142
NETMASK=255.255.255.0
NETWORK=172.16.42.0
BROADCAST=172.16.42.255
GATEWAY=172.16.42.1
ONBOOT=yes

This assumes the IP of your box is 172.16.42.142 with a netmask of 255.255.255.0. Network and broadcast will be set up in the same fashion, using .0 at the end of network and .255 for broadcast. Gateway may fluctuate depending on your own network setup – usually, gateways are located at .1, but your mileage may vary.

/etc/init.d/networking restart

…And yer off.
